DESCRIPTION
The MSP430G2231 is an ultra-low-power microcontroller consisting of several devices featuring different sets of
peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized
to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit
RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally
controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.
The MSP430G2231 has a 10-bit A/D converter and built-in communication capability using synchronous
protocols (SPI or I2C). For configuration details, see Table 1.
Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values,
and then process the data for display or for transmission to a host system.
